The best filters for the 3M HF-800 series are the 3M Secure Click particulate filters matched to your dust and any nuisance odor. The HF-800 half mask takes the D-series filters, which range from P95 to P100 and add hard-case or odor-relief variants. Our top pick is the D3091 P100 for nearly all dust, the D3071 P95 for budget general aerosol, the D3097 for solvent odor, and the D9093 hard case for reuse. This guide is for HF-800 (and FF-800) owners choosing particulate filters by hazard.
Safety-critical point: these are particulate filters. The nuisance-relief versions (D3096 acid gas, D3097 organic vapor) only ease low-level odor — they are not gas protection. For solvent vapor or acid gas at exposure levels, use a Secure Click cartridge such as the D80921 or D80923. And D-series filters fit only Secure Click — see are respirator cartridges universal?

Buyer's Guide: Class First, Then Extras
How they work: all HF-800 filters are Secure Click particulate filters that trap dust, mist and fume mechanically. They differ in efficiency class — N95, P95 or P100 — and in optional extras: a hard case, or a thin carbon layer for nuisance odor relief.
The major decision is the efficiency class. P100 (D3091 and its variants) captures at least 99.97% and is the right call for regulated, high-toxicity dusts such as silica, lead and hexavalent chromium. P95 (D3071, D3078) captures at least 95%, resists oil, and suits oil mist and general aerosol where no substance-specific standard applies. N95 (D7N11) is the budget non-oil option for light dust. Then layer on extras only as needed: a hard case (D9093, D9093C) for reuse and storage, and nuisance odor relief (D3096 acid, D3097 solvent) for comfort.
Compatibility considerations: every D-series filter fits both the HF-800 half masks and the FF-800 full facepieces, but none fit bayonet respirators. Browse the range in P100 filters and 3M filters & cartridges.
Common mistakes and safety limitations: the big ones are using P95/N95 where a standard requires P100, treating nuisance relief as gas protection, and buying odor or hard-case extras you don't need. None of these filters stop gas at exposure levels. Confirm your dust and any standard via how to choose a respirator cartridge.

Comparison Table
| Filter | Protection Type | Compatibility | Best Use | Strengths | Weaknesses | Price |
|---|---|---|---|---|---|---|
| D3091 | P100 | Secure Click HF/FF-800 | Regulated dust | Best all-around | No gas/odor | $$ |
| D3071 | P95 | Secure Click HF/FF-800 | Oil mist, general dust | Cheapest | Not for regulated dust | $ |
| D3097/D3096 | P100 + nuisance OV/acid | Secure Click HF/FF-800 | Dust + odor | P100 + odor comfort | No true gas protection | $$ |
| D9093/D9093C | P100 (hard case / HF) | Secure Click HF/FF-800 | Reuse / HF work | Durable / HF-resistant | Pricier | $$–$$$ |
Common Buying Mistakes
- Using P95/N95 where P100 is required. Silica, lead and hex chrome need the D3091, not the D3071 or D7N11.
- Treating nuisance relief as gas protection. The D3096/D3097 ease odor only — gas at the PEL needs a cartridge.
- Buying extras you don't need. No odor or reuse requirement? The plain D3091 (or D3071) is cheaper.
- Using bayonet 2091/2097 on the HF-800. Only D-series fit — see are respirator cartridges universal?
- Picking the wrong odor type. D3096 = acid, D3097 = solvent; they don't cross over.
- Running a loaded filter too long. Replace when breathing gets hard or the filter is soiled.
Frequently Asked Questions
What filters fit the 3M HF-800 series respirator?
The HF-800 uses 3M Secure Click filters. The particulate options are the D3071 (P95), D3091 (P100), D9093 (P100 hard case) and D9093C (P100 with hydrogen fluoride media), plus nuisance-relief versions: the D3096 (P100 + acid gas odor), D3097 (P100 + organic vapor odor) and the D7N11 (N95). The single-pair D3078 is a P95 for low-volume use. Bayonet 2000-series filters do not fit.
What is the best filter for the HF-800?
For most users the D3091 P100 is the best overall — 99.97% efficiency that covers silica, lead, metal fume and general dust. Drop to the D3071 P95 for oil mist and general aerosol on a budget, add the D3097 for solvent odor or the D3096 for acid odor, and choose the D9093 hard case for reuse programs.
Do I need P95 or P100 on the HF-800?
Use P100 (D3091) for regulated, high-toxicity dusts — silica, lead, hexavalent chromium — and for the best margin generally. P95 (D3071) is acceptable for oil mist and general aerosol where no substance-specific standard requires P100. When in doubt, P100 is the safe default.
Which HF-800 filter is best for welding?
The D3091 P100 for stainless, galvanized and most weld fume; the D3097 if you grind or weld on coated or oily metal (solvent odor). See our dedicated best Secure Click filters for welding guide for the full breakdown.
What do the nuisance-relief filters add?
The D3096 and D3097 add a thin carbon layer that eases a low-level odor — acid gas for the D3096, organic vapor for the D3097 — on top of full P100 particulate protection. The relief is comfort only and is not gas protection at exposure levels.
Do HF-800 filters protect against gas or vapor?
No. These are particulate filters. The nuisance-relief versions ease low-level odor only. For solvent vapor or acid gas at exposure levels you need a Secure Click cartridge such as the D80921 or D80923.
What is the D9093 hard case for?
The D9093 is a P100 filter with the same filtration as the D3091 but in a hard polycarbonate case, suited to multi-shift reuse, toolbox storage and exterior decontamination. The D9093C adds hydrogen-fluoride-resistant media for semiconductor and HF work.
Can I use bayonet 2091 or 2097 filters on the HF-800?
No. The HF-800 takes only Secure Click D-series filters. Bayonet 2000-series filters fit the 3M 6000, 6500 and 7500 series instead. The two systems are not interchangeable.
Are these filters NIOSH approved?
Yes — the D3091, D3096, D3097, D9093 and D9093C are P100, the D3071 and D3078 are P95, and the D7N11 is N95, all NIOSH-approved on the matching Secure Click respirator. Verify the printed approval and follow your written respiratory protection program.
How often should HF-800 filters be replaced?
Replace a particulate filter when breathing becomes noticeably harder, or when it is damaged or soiled, per your facility's schedule. Heavier dust and fume load filters faster. Follow your written respiratory protection program.
Do HF-800 filters also fit the FF-800 full facepiece?
Yes. All Secure Click D-series filters fit both the HF-800 half masks and the FF-800 full facepieces, since both use the same Secure Click connection. The filter choice is the same on either facepiece.
Which HF-800 filter is the best value?
The D3071 P95 is the cheapest for general aerosol and oil mist, and the single-pair D3078 suits low-volume buyers. For P100 work the standard D3091 is the best value; reserve the hard-case D9093 and the specialty D9093C for programs that specifically need them.
Final Recommendation
- Best Overall — D3091 (P100): the right filter for nearly all HF-800 dust work.
- Best Budget — D3071 (P95): oil mist and general aerosol.
- Best Professional — D9093 (P100 hard case): reuse and decon programs.
- Best Specialty — D3097 / D3096: P100 plus odor relief.
Verdict: pick the efficiency class first (P100 D3091 for regulated dust, P95 D3071 otherwise), then add a hard case or odor relief only if you need it — and step up to a cartridge for real gas. Browse the range in P100 Respirator Filters & Cartridges.
